Description

The present invention relates to control technology for allocating hall calls to cars in an elevator.

In elevator control technology, when a user inputs a destination floor using a destination floor registration device provided at the departure hall, the departure floor and destination floor are treated as one hall call, and transportation efficiency is improved. There is a method for assigning an optimum car after consideration (see, for example, Patent Document 1). In this control technology, if one user inputs the destination floor in the destination floor registration device, the correspondence between the assignment to the car and the user becomes one to one. is not wasted, and high transportation efficiency is realized in the elevator.

JP 2020-75771 A

However, in the destination floor registration device, there may be a case where one user inputs the destination floor (calls for the hall) multiple times. And, as such cases, there are cases in which the user inputs the destination floor multiple times as a prank, and cases in which the user re-enters the destination floor for confirmation when, for example, the waiting time becomes long. Furthermore, there may be a case where the user re-enters another destination floor to change the destination floor. In these cases, one user is assigned to a plurality of cars, resulting in wasteful car assignments, which reduces the transportation efficiency of elevators.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to realize high transport efficiency in an elevator that requires input of a destination floor at a landing even if one user inputs the destination floor multiple times.

A control system according to the present invention includes an input unit for inputting a destination floor, a first biometric information acquisition unit, a storage unit, a first determination processing unit, and an allocation processing unit. The first biometric information acquisition unit acquires biometric information for identifying the user from the user who has entered the destination floor with the input unit. The storage unit selectively stores the biometric information acquired by the first biometric information acquiring unit. The first determination processing unit determines whether or not the biometric information acquired by the first biometric information acquisition unit has been saved in the storage unit each time the destination floor is input by the input unit. Then, when the first determination processing unit determines that the biometric information is "not saved", the allocation processing unit uses the destination floor input by the input unit by the user who has the biometric information to access the car. Along with the assignment, the biometric information is stored in the storage unit. On the other hand, when the first judgment processing unit judges that the biometric information is "already saved", the allocation processing unit does not newly allocate the user who has the biometric information, but the existing user. Either perform a quota limit, which maintains the quota, or perform a quota update, which cancels the existing quota and renews the new quota.

According to the above control system, even if there are an unspecified number of users and one of them inputs the destination floor (calling the platform) multiple times, the user's biometric information A one-to-one correspondence between the car allocation and the user is maintained by executing the allocation restriction or the allocation update based on the information.

In the above control system, when the destination floor input by the input unit is used to allocate the car, the allocation processing unit corresponds the destination floor to the biometric information of the user who input the destination floor. It may be further stored in the storage unit with a file attached. In such a configuration, when the first determination processing unit determines that the biometric information is "already saved", the destination floor input by the user having the biometric information through the input unit is stored in the storage unit. It may be further determined whether or not it is the same as the destination floor associated with the biometric information. Then, when the first determination processing unit determines that the destination floors are "same", the allocation processing unit executes allocation restriction, and the first determination processing unit determines that the destination floors are "not the same". If so, an allocation update may be performed.

Here, as a case where one user inputs the destination floor multiple times (calling the hall), (1) the user mischievously inputs the destination floor multiple times, and (2) the waiting time is long. (3) The user re-enters another destination floor to change the destination floor. In cases (1) and (2), the same destination floor is often input, and in case (3), different destination floors are often input. Therefore, when one user inputs the destination floor (calling the hall) multiple times, and if the destination floor is the same, the above-mentioned allocation restriction is executed to prevent unnecessary allocation. avoid occurring. Also, if the destination floors are not the same, the allocation update described above is performed, thereby avoiding wasting existing allocations.

The control system may further include a first notification processing section. The first notification processing unit notifies the user that the allocation already exists when the allocation restriction is executed for the user, and when the allocation update is executed for the user notifies its users that the quota has been updated. By performing such notification, the user who has input the destination floor multiple times can be made aware of the allocation status of himself/herself. In addition, it is possible for a person who mischievously inputs a destination floor multiple times to recognize that multiple inputs (mischievous) are useless because no new allocation occurs.

The control system may further include a second biological information acquisition section, a second determination processing section, and a second notification processing section. The second biometric information acquisition unit acquires the biometric information from a user who has boarded the car. The second determination processing unit determines whether or not the biometric information acquired by the second biometric information acquisition unit has been saved in the storage unit. Then, when the second determination processing unit determines that the biometric information has not been saved, the second notification processing unit determines that the user who boarded the car without an allocation inform that there is

Here, only the biometric information of the user who has been assigned to the car and information related thereto is stored in the storage unit. Therefore, when the second determination processing unit determines that the biometric information acquired by the second biometric information acquisition unit is "already saved", the user who has the biometric information is Conversely, if it is determined that it is "not saved", it can be determined that there is no allocation for the user in any car. Therefore, according to the determination by the second determination processing unit, among the users in the car, there are users who boarded without any allocation (that is, users who boarded without inputting the destination floor). In such a case, it becomes possible to detect the presence of such a user (a user who has boarded the vehicle illegally). Then, when the presence of such a user is detected, the above-mentioned notification is made to inform the user that some kind of operation (that is, input of the destination floor) is required in order to board the car. can be given an opportunity to recognize

In the above control system, when the destination floor input by the input unit is used to allocate the car, the allocation processing unit converts the information of the car into the biometric information of the user who entered the destination floor. They may be further stored in the storage unit in association with each other. In such a configuration, when the second determination processing unit determines that the biometric information is "already saved", the information of the car in which the user who has the biometric information boarded is stored in the storage unit. It may be further determined whether or not there is a match with the car information associated with . Then, when the second determination processing unit determines that the information on the car in which the user has boarded does not match, the second notification processing unit notifies the user in the car of the car. It may be notified that there is a user who has mistakenly boarded the vehicle.

According to such a configuration, when the second judgment processing unit judges that the car information "matches", it judges that the user correctly boarded the assigned car. Conversely, if it is determined that they do not match, it can be determined from that determination that the user has erroneously boarded a different car from the assigned car (i.e., has boarded the wrong car). . Therefore, according to such a judgment, if there is a user who has mistakenly boarded the car (that is, a user who has mistakenly boarded the car) among the users in the car, such a user Presence can be detected. By performing the above notification when the presence of such a user is detected, it is possible to give the user an opportunity to notice that he or she has boarded the wrong vehicle.

In the above control system, if the second determination processing unit determines that the information on the car in which the user has boarded does not match, the information is stored in the car before notification by the second notification processing unit. The department may further determine whether there is an assignment made using the same destination floor as the destination floor associated with the biometric information of the user. Then, when the second determination processing unit determines that the assignment using the same destination floor does not exist, the second notification processing unit determines that the user who is going to the destination floor is not boarding by mistake. You can let us know something.

According to such a configuration, when the second judgment processing unit judges that it does not exist, the user who is going to the destination floor to which the allocation does not exist is the user who boarded by mistake. can be judged. Therefore, by performing the above notification, it is possible to make the user who boarded the wrong vehicle realize that he or she himself boarded the wrong vehicle.

Advantageous Effects of Invention According to the present invention, in an elevator that requires input of a destination floor at a hall, high transportation efficiency is realized even when one user inputs the destination floor multiple times.

[1] Configuration of Elevator and Its Control System FIG. 1 is a conceptual diagram showing the configuration of an elevator to which an embodiment of the control system according to the present invention is applied. As shown in FIG. 1 , the elevator includes a car 100 , a destination floor registration device 101 , an elevator control device 102 and a group management control device 103 . The configuration of each unit will be specifically described below. Although not particularly limited, FIG. 1 shows an elevator configuration in which three cars 100 are provided.

<Destination floor registration device>
The destination floor registration device 101 is installed at the boarding hall of each floor, and device information Pd1 for identifying each is set in the destination floor registration device 101 . Further, each destination floor registration device 101 is provided with an input unit 1 for inputting the destination floor Fd and a first biometric information acquisition unit 2A.

In this embodiment, the input unit 1 is configured by a touch panel 10 that also functions as a display unit. Then, a screen for inputting the destination floor Fd (such as a screen on which the destination floor Fd can be selected; see FIG. 4A) is displayed on the touch panel 10, so that the user can Input (selection, etc.) of the destination floor Fd becomes possible. In addition, various types of information (such as information on the car 100 in which the user should ride; see FIGS. 4B and 4C) are displayed as appropriate on the touch panel 10 . The input unit 1 is not limited to the touch panel 10, and may be configured separately from the display unit. For example, the input unit 1 may be composed of mechanical buttons for inputting the destination floor Fd, and the display unit may be composed of a display-only monitor.

The first biometric information acquiring unit 2A acquires biometric information Pi for identifying the user from the user who has entered the destination floor Fd with the input unit 1 . In this embodiment, the first biometric information acquisition unit 2A is an imaging device that acquires a face image of the user as the biometric information Pi. The first biometric information acquisition unit 2A may be appropriately changed to a device that acquires biometric information Pi (for example, information on fingerprints, retinas, etc.) other than face images.

The destination floor Fd input by the input unit 1 and the biological information Pi obtained by the first biological information obtaining unit 2A are used in the first control process executed by the group supervisory control device 103 (when the user inputs the destination floor Fd). Control processing to be executed (details will be described later). Therefore, the destination floor registration device 101 registers the destination floor Fd every time the user inputs the destination floor Fd through the input unit 1 and the first biometric information acquisition unit 2A acquires the biometric information Pi from the user. and biological information Pi are transmitted to the group supervisory control device 103 as information necessary for the first control process (see FIG. 1).

Here, the destination floor registration device 101 does not acquire the biometric information Pi from the user even though the user has input the destination floor Fd through the input unit 1 (for example, the face is If it cannot be recognized), the touch panel 10 may display a message to that effect or a message prompting re-input of the destination floor Fd. As a result, the user can recognize that it is necessary to provide his/her own biometric information Pi when entering the destination floor Fd, and respond by turning his or her face toward the first biometric information acquisition unit 2A. can take As a result, it is possible to reliably acquire the biometric information Pi from the user when entering the destination floor Fd.

In addition, the destination floor registration device 101 also registers the device information Pd1 of the destination floor registration device 101 so that the group supervisory control device 103 recognizes the location of itself, which is the transmission source of the destination floor Fd and the biometric information Pi. It is transmitted to the group supervisory control device 103 together with Fd and the biometric information Pi. The destination floor registration device 101, as the device information Pd1, group-manages the device information of the first biometric information acquisition unit 2A provided therein (that is, the first biometric information acquisition unit 2A that has read the biometric information Pi). You may transmit to the control apparatus 103. FIG.

<Elevator controller>
Elevator controllers 102 are provided for each car 100 and control the operation of the corresponding car 100 . In addition, device information Pd2 for identifying each of the elevator control devices 102 is set. The elevator controller 102 is centrally managed and controlled by the group supervisory controller 103 .

<Group supervisory control device>
The group supervisory control device 103 has a storage section 3 and a control section 4 . The storage unit 3 is a memory such as a ROM or a RAM, and various information necessary for elevator control is stored in the storage unit 3 . In this embodiment, device management data D1 and information management data Dp are stored in the storage unit 3 as information necessary for elevator control. Here, the device management data D1 is data in which other information related to the destination floor registration device 101 is previously associated with each device information Pd1 of the destination floor registration device 101 and stored. In addition, the information management data Dp selectively stores the biometric information Pi acquired by the first biometric information acquiring unit 2A, and each time, stores other information associated with the biometric information Pi. Data.

FIG. 2A is a conceptual diagram showing an example of the device management data D1. In the device management data D1, the device address Pa and the installation floor Fs are associated in advance for each device information Pd1. Here, the device address Pa is an address (such as an IP address) used for operation control of the destination floor registration device 101 identified by the device information Pd1 and information transmission to the destination floor registration device 101. The installation floor Fs is the floor where the destination floor registration device 101 identified by the device information Pd1 is installed.

FIG. 2B is a conceptual diagram showing an example of the information management data Dp. In this information management data Dp, a departure floor Fc, a destination floor Fd, car information Pg, and an allotted time Tg are associated with each biometric information Pi. Here, the departure floor Fc is the floor where the user identified by the biometric information Pi gets on the car 100 . In this embodiment, the installation floor Fs of the destination floor registration device 101 used by the user to input the destination floor Fd is used as the departure floor Fc. The destination floor Fd is the floor input by the user identified by the biometric information Pi through the input unit 1 of the destination floor registration device 101 . The car information Pg is information (numbers, symbols, etc.) for identifying the car 100 to which the departure floor Fc and the destination floor Fd are assigned as one hall call. The allocation time Tg is the time when the hall call is allocated to the car 100 .

Then, in the present embodiment, among the information stored in the information management data Dp, those after a predetermined time (for example, 10 minutes) has passed from the allocation time Tg (biological information Pi and all related information) are sequentially , is deleted from the information management data Dp.

The control unit 4 is a processing device such as a CPU, and stores information (destination floor Fd, biometric information Pi, and device information Pd1) necessary for the first control processing (control processing executed when the destination floor Fd is input by the user). ) is received from the destination floor registration device 101, a first determination process, an allocation process, and a first notification process are executed as the first control process. Specifically, it is as follows.

In the first determination process, the control unit 4 determines whether or not the biometric information Pi included in the received information (hereinafter referred to as "received information Pr1") has been saved in the information management data Dp. Then, if the control unit 4 determines that the biological information Pi included in the received information Pr1 is "not saved", it performs allocation processing to the destination floor Fd included in the received information Pr1 (that is, The destination floor Fd) input by the input unit 1 by the user having the biometric information Pi is used to allocate to the car 100 , and the biometric information Pi is stored in the storage unit 3 .

Through these processes, the control unit 4 uses the biometric information Pi of each user who has entered the destination floor Fd with the input unit 1 to determine whether the user has already been assigned to the car 100. It is possible to judge whether the user is a user who Therefore, when the control unit 4 determines that the biometric information Pi included in the received information Pr1 is "already saved", as a series of flow in the allocation process, the user having the biometric information Pi It enforces allocation limits that maintain existing allocations without making new allocations.

According to such a process, even if there are an unspecified number of users and one of them inputs the destination floor Fd (calling the platform) multiple times, the user's biometric By executing the allocation restriction based on the information Pi, the one-to-one correspondence between the allocation to the car 100 and the users is maintained. Therefore, the group supervisory control device 103 can accurately grasp the number of assigned cars to the car 100 . Therefore, even when one user inputs the destination floor Fd a plurality of times, the elevator achieves high transportation efficiency.

Then, when the control unit 4 executes the allocation restriction for the user, the control unit 4 notifies the user that the allocation to the car 100 already exists as the first notification process. In this embodiment, the control unit 4 displays a message on the touch panel 10 to inform the user that the allocation to the car 100 already exists (see FIG. 4(C)). Note that the notification to the user may be performed by means other than the display on the touch panel 10 (audio output from a speaker, etc.).

By making such notification, the user who has input the destination floor Fd a plurality of times can be made aware of his/her allocation status. In addition, it is possible for a person who mischievously inputs the destination floor Fd multiple times to recognize that multiple inputs (mischievous) are useless because no new allocation occurs.

In this embodiment, the first determination processing, the allocation processing, and the first notification processing are executed by the first determination processing section 41A, the allocation processing section 42, and the first notification processing section 43A, which are configured in the control section 4, respectively. (See FIG. 1). Specifically, these processing units are composed of software by causing a processing device (such as a CPU), which is the control unit 4, to execute programs, and such programs are stored in the storage unit 3. ing. The program may be stored in a portable storage medium (for example, flash memory) in a readable state, and read from the storage medium may be stored in the storage unit 3. It may be saved in a server or the like so as to be downloadable, and the one downloaded from the server may be saved in the storage unit 3 . Note that the above processing unit may be configured by hardware by constructing the control unit 4 in the group supervisory control device 103 with a circuit.

In such an elevator, a control system according to an embodiment of the present invention is configured by the input unit 1, the first biological information acquisition unit 2A, the storage unit 3, and the control unit 4. Hereinafter, as control processing executed in such a control system, first control processing (including first determination processing, allocation processing, and first notification processing) executed by the group supervisory control device 103 (control unit 4) will be described in detail.

[2] Control processing executed by the control system <First control processing>
FIG. 3 is a flow chart showing the first control process executed by the group supervisory control device 103. As shown in FIG. The first control process is started when the group supervisory control device 103 receives information necessary for the process (including the destination floor Fd, the biometric information Pi, and the device information Pd1) from the destination floor registration device 101.

When the first control process is started, the control unit 4 of the group supervisory control device 103 converts the biometric information Pi and the destination floor Fd included in the information (received information Pr1) received from the destination floor registration device 101 into Substitute into the biometric information variable X1 and the destination floor variable X2 (step S101). Here, the biological information variable X1 and the destination floor variable X2 are variables in which the biological information Pi and the destination floor Fd are appropriately stored in the course of the first control process.

Further, the control unit 4 uses the device information Pd1 included in the received information Pr1 to read the device address Pa and installation floor Fs corresponding to the device information Pd1 from the device management data D1 (step S102). Note that step S102 may be executed before step S101.

Next, the control unit 4 determines whether the user who has input the destination floor Fd through the input unit 1 is a user already assigned to the car 100, so that the value of the biometric information variable X1 It is determined whether or not the biometric information Pi substituted for the biometric information variable X1 in step S101 has been stored in the information management data Dp (step S103). Specifically, the control unit 4 can recognize from the face image data substituted as the biometric information Pi in the biometric information variable X1 in the face image data stored as the biometric information Pi in the information management data Dp. It is determined whether or not there exists a user that can recognize the same user as the user.

Then, when the control unit 4 determines that "not stored (No)" in step S103, the user who has input the destination floor Fd through the input unit 1 is assigned to the car 100. is a nonexistent user (new user), the user is newly assigned to the car 100 . Specifically, it is as follows.

The control unit 4 first sets the state variable W to "new" (step S111). Here, the state variable W is a variable representing the state of allocation to the car 100, and is set to "new" when a new allocation is made, and when there is an existing allocation as described later. is set to "existing". Note that step S111 may be executed after step S112 or step S113, which will be described below, as long as it is before step S130, which will be described later.

After executing step S111, the control unit 4 uses the installation floor Fs read in step S102 as the departure floor Fc, and the values of the departure floor Fc and the destination floor variable X2 (that is, the value of the destination floor variable X2 in step S101 Destination floor Fd) is assigned to any one car 100 as one hall call (step S112). Then, the control unit 4 substitutes the car information Pg of the allocated car 100 into the allocation information variable X3, and substitutes the current time T when the allocation to the car 100 is executed into the allocation time Tg. Here, the allocation information variable X3 is a variable in which the car information Pg is appropriately stored in the course of the first control process.

Thereafter, the control unit 4 stores the value of the biometric information variable X1 (the biometric information Pi substituted for the biometric information variable X1 in step S101) in the information management data Dp (step S113). At this time, the control unit 4 associates the value of the biological information variable X1 (biological information Pi) with the value of the departure floor Fc (set floor Fs read in step S102), the value of the destination floor variable X2 (destination Destination floor Fd assigned to floor variable X2), value of assignment information variable X3 (car information Pg assigned to assignment information variable X3 in step S112), and value of assignment time Tg (assignment to car 100 in step S112) The current time T) at the time of execution is further stored in the information management data Dp.

In the present embodiment, the control unit 4 selects information stored in the information management data Dp after a predetermined period of time (for example, 10 minutes) from the allocation time Tg (biological information Pi and all information related thereto). ) are sequentially deleted from the information management data Dp (not shown in the flowchart of FIG. 3).

On the other hand, when the control unit 4 determines that "it has been saved (Yes)" in step S103, the user who has input the destination floor Fd through the input unit 1 can enter the car 100. It can be determined that the quota already exists for a user. In this case, the control unit 4 does not newly allocate the user (step S112), but imposes an allocation restriction that maintains the existing allocation. In the present embodiment, the control unit 4 does not perform new allocation (step S112), thereby limiting the allocation, and performs only the necessary preparations for the processing of step S130 (first notification processing) to be described later. The process proceeds to step S130. Specifically, it is as follows.

The control unit 4 first sets the state variable W to "existing" (step S121). Note that step S121 may be executed after step S122 described below as long as it is before step S130 described later.

Thereafter, the control unit 4 retrieves information (destination floor Fd and car information Pg) from the information management data Dp for notifying the user of the existing allocation without making a new allocation. Read out (step S122). Specifically, the control unit 4 uses the value of the biometric information variable X1 (the biometric information Pi substituted for the biometric information variable X1 in step S101) to correspond to the value (the biometric information Pi) from the information management data Dp. Destination floor Fd and car information Pg are read. By substituting the read destination floor Fd into the destination floor variable X2, the control unit 4 substitutes the value of the destination floor variable X2 in step S101 (that is, the value entered by the user at that time). Destination floor Fd) is rewritten with the one read in step S122 (that is, the destination floor Fd already assigned to the user). Also, the control unit 4 substitutes the read cage information Pg for the allocation information variable X3.

After executing either step S113 or S122, the control unit 4 transmits information necessary for notifying the user to the destination floor registration device 101 specified by the device address Pa read out in step S102 (step S130). Specifically, the control unit 4 sets the value of the destination floor variable X2 (the destination floor Fd substituted for the destination floor variable X2 in step S101 or S122), the value of the allocation information variable X3 (the allocation information variable The car information Pg substituted for X3) and the value of the state variable W ("new" set in step S111 or "existing" set in step S121) are used as information necessary for informing the user of the destination. It is transmitted to the floor registration device 101 (see FIG. 1).

Then, when the destination floor registration device 101 receives information (including the destination floor Fd, the car information Pg, and the state variable W) necessary for notifying the user from the group supervisory control device 103, Notify users of the content.

Specifically, when the value of the state variable W is "new", the destination floor registration device 101 displays the received destination floor Fd and car information Pg on the touch panel 10 (see FIG. 4B). . This allows the user to recognize the car 100 in which he or she should ride. At this time, as shown in FIG. 4B, a message may be displayed on the touch panel 10 to notify the user that the car 100 identified by the car information Pg has been assigned. .

On the other hand, when the value of the state variable W is "existing", the destination floor registration device 101, along with the received destination floor Fd and car information Pg, indicates that the car 100 identified by the car information Pg has been assigned. A message is displayed on the touch panel 10 to notify the user that the file already exists (see FIG. 4C). As a result, the user who has input the destination floor Fd multiple times can be made aware of his/her allocation status. In addition, it is possible for a person who mischievously inputs the destination floor Fd multiple times to recognize that multiple inputs (mischievous) are useless because no new allocation occurs.

Note that the notification to the user may be performed by means other than the display on the touch panel 10 (audio output from a speaker, etc.).

According to such a first control process, even if there are an unspecified number of users and one of them inputs the destination floor Fd (calls for the hall) multiple times, the By executing the allocation restriction based on the biometric information Pi of the person, the one-to-one correspondence between the allocation to the car 100 and the user is maintained. Therefore, the group supervisory control device 103 can accurately grasp the number of assigned cars to the car 100 . Therefore, even when one user inputs the destination floor Fd a plurality of times, the elevator achieves high transportation efficiency.

[3] Modification [3-1] First Modification Assuming a case where one user inputs the destination floor Fd multiple times (calling the hall), (1) the user mischievously inputs the destination floor Fd multiple times. (2) For example, when the waiting time is long, the user re-enters the destination floor Fd for confirmation; A case such as re-inputting the destination floor Fd of is conceivable. In cases (1) and (2), the same destination floor Fd is often input, and in case (3), different destination floors Fd are often input.

In the first control process described in the above embodiment, allocation restriction is executed in any of cases (1) to (3). may be changed as appropriate. As an example, the first control process is the same as in the above embodiment when one user inputs the destination floor Fd (calls to the hall) a plurality of times and the destination floor Fd is the same. If the destination floors Fd are not the same after the allocation restriction is executed, the allocation may be changed to cancel the existing allocation and then execute the allocation update to make a new allocation.

Specifically, as the first determination process in the first control process, the control unit 4 determines that the target biometric information Pi has been saved (Yes) in step S103. The destination floor Fd input by the user having the information Pi through the input unit 1 of the destination floor registration device 101 (that is, the destination floor Fd substituted for the destination floor variable X2 in step S101) is registered in the information management data Dp as the biometric It may be further determined whether or not it is the same as the destination floor Fd associated with the information Pi (that is, the destination floor Fd read in step S122). Then, the control unit 4 may execute allocation restriction when judging that they are “identical”, and may execute allocation update when judging that they are “not identical”. Hereinafter, this example will be described in detail as a first modified example.

<First control process>
FIG. 5 is a flow chart showing the first control process executed in the first modified example. In this modification, in step S122, the control unit 4 substitutes the destination floor Fd read from the information management data Dp into the read information variable Z0 instead of substituting the destination floor variable X2. Here, the read information variable Z0 is a variable in which the destination floor Fd among the information read from the information management data Dp in the first control process is stored.

After executing step S122, the control unit 4 determines that the value of the destination floor variable X2 (that is, the destination floor Fd substituted for the destination floor variable X2 in step S101) becomes the value of the read information variable Z0 (that is, the read information It is determined whether or not it is the same as the destination floor (Fd) substituted for the variable Z0 (step S140). Based on this determination, the control unit 4 determines that the destination floor Fd input by the user having the target biometric information Pi through the input unit 1 of the destination floor registration device 101 corresponds to the biometric information Pi in the information management data Dp. It can be determined whether or not it is the same as the attached destination floor Fd.

Then, if the control unit 4 determines "they are the same (Yes)" in step S140, it proceeds to step S130 as it is, thereby maintaining the existing allocation without making a new allocation (allocation limit).

On the other hand, if the control unit 4 determines "not the same (No)" in step S140, it cancels the existing allocation and then performs new allocation (allocation change). Then, when the allocation change is executed for the user, the control unit 4 informs the user that the allocation to the car 100 has been updated as the first notification process in the first control process. Notify (step S130). Specifically, it is as follows.

If the control unit 4 determines that they are not the same (No) in step S140, it first sets the state variable W to "change" (step S141). Note that step S141 may be executed after step S142 or step S143, which will be described below, as long as it is before transition to step S112, which will be described later.

Next, the control unit 4 selects a user who can be recognized from the value of the biometric information variable X1 (that is, the biometric information Pi substituted for the biometric information variable X1 in step S101) in the information stored in the information management data Dp. The biometric information Pi with which the same user can be recognized and all related information are deleted from the information management data Dp (step S142). Also, the control unit 4 cancels the existing allocation for that user (step S143). Note that the execution order of steps S142 and S143 may be reversed.

After that, the control unit 4 shifts to step S112 to newly allocate the cars 100 using the value of the destination floor variable X2 (that is, the destination floor Fd substituted for the destination floor variable X2 in step S101). Run. And the control part 4 transfers to step S130 through step S113.

In this case, at step S130, the control section 4 selects the destination floor Fd substituted for the destination floor variable X2 at step S101 and the car information Pg substituted for the allocation information variable X3 at step S112 as information necessary for notification to the user. , and “change” set to the state variable W in step S141 are transmitted to the destination floor registration device 101 . When the destination floor registration device 101 receives the information from the group control device 103, the destination floor registration device 101 informs the user that the allocation to the car 100 has been updated together with the received destination floor Fd and car information Pg. A message to convey is displayed on the touch panel 10 (see FIG. 6).

According to the first control process as described above, when one user inputs the destination floor Fd (calls to the hall) a plurality of times and the destination floor Fd is the same, allocation restriction is executed. By doing so, wasteful allocation is avoided. Also, if the destination floors Fd are not the same, updating the allocation is performed to avoid wasting the existing allocation. In this modified example, by selectively executing allocation restriction and allocation update in this way, the one-to-one correspondence between the allocation to the car 100 and the user is maintained.

It should be noted that the first control process described in the present modification can be performed even when one user inputs the destination floor Fd (calling the hall) multiple times and the destination floor Fd is the same. Instead of the limitation, it may be appropriately changed to execute allocation update (that is, execute allocation update in any of the above cases (1) to (3)).

[3-2] Second modification <Configuration of elevator and its control system>
FIG. 7 is a conceptual diagram showing the configuration of an elevator to which the control system according to the second modified example is applied. As shown in FIG. 7 , each car 100 may be provided with a second biological information acquiring section 2B and an output section 5 .

Here, the second biometric information acquisition unit 2B acquires biometric information Pi for identifying the user from the user who got on the car 100 . In this embodiment, the second biometric information acquisition unit 2B is an imaging device that acquires a face image of the user as the biometric information Pi, like the first biometric information acquisition unit 2A. The second biometric information acquisition unit 2B may be appropriately changed to a device that acquires biometric information Pi (for example, information on fingerprints, retinas, etc.) other than face images. Further, in the present embodiment, the output unit 5 is a speaker, and notifies the user in the car 100 of various information by voice. Note that the output unit 5 is not limited to one that outputs sound, and may be appropriately changed to a device (such as a monitor) that can notify the user of various information by other means.

Then, the biological information Pi acquired by the second biological information acquisition unit 2B is used as the second control process executed by the group supervisory control device 103 (the control process executed when the user gets into the car 100. For details, is used later). Therefore, each elevator control device 102 obtains the biometric information Pi acquired by the second biometric information acquisition unit 2B provided in the car 100 every time a user gets on the car 100 controlled by the elevator control device 102, 2 is transmitted to the group supervisory control device 103 as information necessary for control processing (see FIG. 7).

In addition, the elevator control device 102 controls the elevator control device 103 so that the group supervisory control device 103 recognizes the position of itself, which is the transmission source of the biological information Pi, and which car 100 it is controlling. The device information Pd2 of the device 102 and the corresponding car information Pg of the car 100 are also transmitted to the group supervisory control device 103 together with the biometric information Pi.

In such an elevator, the control system according to this modification includes the input unit 1, the first biometric information acquisition unit 2A, the storage unit 3, and the control unit 4, and further includes the second biometric information acquisition unit 2B. be. In addition to the first control process (control process executed when the user inputs the destination floor Fd), the control unit 4 performs the second control process (control process executed when the user gets on the car 100). ). Specifically, each time the control unit 4 receives information necessary for the second control process (including the biological information Pi, the device information Pd2, and the car information Pg) from the elevator control device 102, the control unit 4 performs the second control process. , the second determination process and the second notification process are executed. More specifically, it is as follows.

In the second determination process, the control unit 4 determines whether or not the biometric information Pi included in the received information (hereinafter referred to as "received information Pr2") has been saved in the information management data Dp. Here, the information management data Dp stores only the biometric information Pi of the user assigned to the car 100 and information related thereto. Therefore, in the second determination process, when the control unit 4 determines that the biometric information Pi included in the received information Pr2 is "already saved", the use of the biometric information Pi is determined based on that determination. If it is determined that the user has an assignment to any of the cars 100, and conversely, if it is determined that "it is not saved", then it is determined that the user is not assigned to any car 100. can be determined not to exist.

Then, when the control unit 4 determines that the biometric information Pi included in the received information Pr2 is "unsaved", as the second notification process, identification is performed using the car information Pg included in the received information Pr2. The user in the car 100 to be assigned is notified through the output unit 5 that there is a user who boarded without an allocation (user who boarded illegally).

In this modification, the second determination processing and the second notification processing are executed by a second determination processing section 41B and a second notification processing section 43B, respectively, which are configured within the control section 4 (see FIG. 7). Note that these processing units may be configured with software or hardware, like the other processing units (the first determination processing unit 41A, etc.).

Details of the second control process (including the second determination process and the second notification process) executed by the group supervisory control device 103 (control unit 4) will be described below as the control process executed by the control system of the second modified example. will be explained.

<Second control processing>
FIG. 8 is a flow chart showing the second control process executed in the second modified example. The second control process is started when the group supervisory control device 103 receives information necessary for the process (including the biological information Pi, the device information Pd2, and the car information Pg) from the elevator control device 102 .

When the second control process is started, the control unit 4 of the group supervisory control device 103 converts the biometric information Pi and car information Pg included in the information received from the elevator control device 102 (receiving information Pr2) into biometric information. Substitute into information variable Y1 and car information variable Y2 (step S201). Here, the biometric information variable Y1 and the car information variable Y2 are variables in which the biometric information Pi and the car information Pg are appropriately stored in the process of the second control process.

Next, the control unit 4 uses biometric information to determine whether the user who got on the car 100 is a user who is assigned to any car 100 including the car 100 . It is determined whether or not the value of the variable Y1 (that is, the biometric information Pi substituted for the biometric information variable Y1 in step S201) has been saved in the information management data Dp (step S202). Specifically, the control unit 4 can recognize the face image data stored as the biometric information Pi in the information management data Dp from the face image data substituted as the biometric information Pi for the biometric information variable Y1. It is determined whether or not there exists a user that can recognize the same user as the user.

Then, when the control unit 4 determines that "it has been saved (Yes)" in step S202, the user who got on the car 100 has any information including the car 100. to the car 100 can be determined. In this case, the control unit 4 allows the user to board the vehicle.

On the other hand, when the control unit 4 determines that "not saved (No)" in step S202, it informs the user who has boarded the car 100 of which ride including the car 100. It can be determined that there is no allocation in car 100 either. In this case, the control unit 4, as information necessary for notifying the user in the car 100, uses the illegal boarding signal S1 as the elevator control device 102 specified by the device information Pd2 included in the received information Pr2. (step S203).

When the elevator control device 102 receives the illegal boarding signal S1 from the group supervisory control device 103, the elevator control device 102 determines whether the user in the elevator car 100 controlled by the elevator control device 102 has boarded in a state where there is no allocation. It is notified through the output unit 5 that there is (a user who boarded the vehicle illegally).

According to such a second control process, among the users in the car 100, there is a user who boarded without any allocation (that is, a user who boarded without inputting the destination floor Fd). In such a case, it becomes possible to detect the presence of such a user (a user who has boarded the vehicle illegally). When the existence of such a user is detected, the above-mentioned notification is given so that the user is required to perform some operation (that is, input the destination floor Fd) in order to board the car 100. It can give you an opportunity to recognize

[3-3] Third Modification In the second control process described in the second modification, when the control unit 4 determines that "it has been saved (Yes)" in step S202 (FIG. 8), , it can be determined that the user who boarded the car 100 is assigned to any car 100 including the car 100 concerned. However, among such users, there are users who mistakenly board a car 100 other than the car 100 to which they should board (that is, the car 100 to which they are assigned). may be

Therefore, the second control process may be appropriately changed to one capable of detecting the existence of a user who has mistakenly boarded another car 100 . As an example, in the second control process, when a user gets on the car 100 and the user is a user who is assigned to any car 100, the user By comparing the car information Pg of the car 100 in which the user boarded and the car information Pg of the car 100 assigned to the user, it is determined whether or not the user has boarded the wrong car. good.

Specifically, as the second determination process in the second control process, the control unit 4 determines that the target biometric information Pi has been saved (Yes) in step S202. It may be further determined whether or not the car information Pg of the car 100 in which the user having the information Pi boarded matches the car information Pg associated with the biometric information Pi in the information management data Dp. . According to such judgment, when the control unit 4 judges that "they match", it can judge that the user has correctly boarded the assigned car 100 based on the judgment. No", it can be determined that the user has erroneously boarded a car 100 other than the assigned car 100 (that is, the user has boarded the wrong car).

Then, when the control unit 4 determines that the car information Pg of the car 100 in which the user has boarded does not match, the control unit 4 performs the use of the car 100 as the second notification process in the second control process. The user may be notified through the output unit 5 that there is a user who has mistakenly boarded the car 100 .

Hereinafter, this example will be described in detail as a third modified example.

<Second control processing>
FIG. 9 is a flow chart showing the second control process executed in the third modified example. In this modification, the control unit 4 determines that the value of the biometric information variable Y1 (that is, the biometric information Pi substituted for the biometric information variable Y1 in step S201) is "saved (Yes)" in step S202. In this case, first, in order to specify the car 100 assigned to the user having that value (biometric information Pi), the car information Pg corresponding to the value (biometric information Pi) is read from the information management data Dp ( step S211). Then, the control unit 4 substitutes the read car information Pg for the read information variable Z1. Here, the read information variable Z1 is a variable in which the car information Pg among the information read from the information management data Dp in the second control process is stored.

After executing step S211, the control unit 4 determines that the value of the cage information variable Y2 (that is, the cage information Pg substituted for the cage information variable Y2 in step S201) becomes the value of the readout information variable Z1 (that is, the readout information in step S211). It is determined whether or not it matches the cage information Pg) substituted for the variable Z1 (step S212). Based on this determination, the control unit 4 determines whether the car information Pg of the car 100 in which the user having the target biometric information Pi has boarded matches the car information Pg of the car 100 assigned to the user. can decide whether or not

Then, if the control unit 4 determines “match (Yes)” in step S212, it can determine that the user has correctly boarded the assigned car 100 based on that determination. In this case, the control unit 4 permits boarding of the car 100 as it is.

On the other hand, if the control unit 4 determines that "they do not match (Yes)" in step S212, it determines that the user has mistakenly boarded a car 100 other than the assigned car 100. It can be determined that the vehicle has been boarded by mistake (that is, it is an incorrect boarding). In this case, the control unit 4, as information necessary for notifying the user in the car 100, sends the wrong boarding signal S2 to the elevator control device 102 specified by the device information Pd2 included in the received information Pr2. (step S213).

Then, when the elevator control device 102 receives an erroneous boarding signal S2 from the group supervisory control device 103, the elevator control device 102 notifies the user in the car 100 controlled by the elevator control device 102 of the user who has boarded the car 100 by mistake. It is notified through the output unit 5 that the

According to such a second control process, when there is a user who has mistakenly boarded the car 100 among the users in the car 100 (that is, a user who has mistakenly boarded the car 100), such a It becomes possible to detect the presence of the user. By performing the above notification when the presence of such a user is detected, it is possible to give the user an opportunity to notice that he or she has boarded the wrong vehicle.

[3-4] Fourth Modification In the second control process described in the third modification above, when the control unit 4 determines that "does not match (No)" in step S212 (FIG. 9), Based on this determination, it can be determined that the user has erroneously boarded a car 100 other than the assigned car 100 (that is, has boarded the wrong car). On the other hand, there is a case where another user whose destination floor Fd is the same as that of the user is boarding the car 100 in which the user has boarded by mistake. In such a case, even if the user gets on another car 100 by mistake, the car 100 stops at the destination floor Fd of the user. For this reason, it may be preferable from the viewpoint of transportation efficiency to permit boarding of the car 100 as it is.

Therefore, the second control process is executed only when there is no allocation performed using the same destination floor Fd as the destination floor Fd of the user in the car 100 in which the user boarded the wrong car. Conversely, if such an allocation exists, it may be appropriately changed to allow boarding of the car 100 as it is.

Specifically, when the control unit 4 determines that the car information Pg of the car 100 in which the user boarded does not match as the second determination process in the second control process, Allocation performed using the same destination floor Fd as the destination floor Fd associated with the biometric information Pi of the user in the information management data Dp in the car 100 before notification of the presence of the passenger. It may further be determined whether there is a

Then, only when the controller 4 determines that there is no allocation performed using the same destination floor Fd, as the second notification processing in the second control processing, the control unit 4 tries to go to the destination floor Fd. It may be notified through the output unit 5 that the user who is in the vehicle is boarding by mistake.

Hereinafter, this example will be described in detail as a fourth modified example.

<Second control processing>
FIG. 10 is a flow chart showing the second control process executed in the fourth modified example. In this modification, in step S211, the control unit 4 selects the car 100 assigned to the user having the value of the biometric information variable Y1 (that is, the biometric information Pi substituted for the biometric information variable Y1 in step S201). In addition to specifying, in order to specify the destination floor Fd used for allocation to the car 100, the destination floor Fd corresponding to the value (biometric information Pi) is further read from the information management data Dp. Then, the control unit 4 substitutes the read destination floor Fd for the read information variable Z2. Here, the read information variable Z2 is a variable in which the destination floor Fd among the information read from the information management data Dp in the second control process is stored.

After execution of step S211, if the control unit 4 determines "does not match (Yes)" in step S212, the value of the car information variable Y2 (that is, the car assigned to the car information variable Y2 in step S201) Information Pg Here, in the car 100 having the car information Pg of the car 100 in which the user boarded by mistake, the value of the read information variable Z2 (that is, the destination floor Fd substituted for the read information variable Z2 in step S211). Here, it is further determined whether or not there is an allocation performed using the same destination floor Fd as the destination floor Fd of the user who boarded by mistake (step S220).

Then, even if the user has boarded the wrong car 100, if the control unit 4 determines that "there exists (Yes)" in step S220, the user Since it can be determined that the car 100 in which the user has boarded by mistake stops at the destination floor Fd of the user, boarding of the car 100 is permitted as it is.

On the other hand, if the control unit 4 determines that "does not exist (Yes)" in step S220, the user who is going to the destination floor Fd for which no allocation exists is the user who boarded by mistake. It can be determined that there is Therefore, in step S213, the control unit 4 transmits an erroneous boarding signal S2 to the elevator control device 102, thereby notifying through the output unit 5 that the user who is going to the destination floor Fd is boarding by mistake. do. This makes it possible for the user who has boarded the wrong vehicle to notice that he or she has boarded the wrong vehicle.
